HOT-AIR REGISTER.

Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed April 4, 1905. Serial No. 253,781.

To a whom, it may concern: I

Be it known that I, JOHN T. SLATER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hot-Air Registers; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to hot-air registers; and the invention consists in a register having a face-plate and blades beneath the same adapted to turn on individual pivots and open and close apertures in the face-plate and in novel means for operating said blades, all substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan or top view of the register closed; and Fig. 2 is a cross-section thereof on line as 01:, Figs. 1 and 3. Fig. 3 is across-section on line y Fig. 1, which is at right angles to Fig. 2 and off the center of the register and with the blades closed. Fig. A is a cross-section on the same line as Fig. 3, but with the blades open. Fig. 5 is a sectional elevation on line a a, Fig. l, traversing the slot between the sides of the central flanges across the register. Fig. 6 is a perspective view of one of the blades.

As thus shown, A represents the face-plate, which is of grid or grate pattern, as usual, and may be struck up from sheet metal or made in a single casting of suitable weight. If of sheet metal, it will necessarily be of two sheets at least, as otherwise it would be impossible to obtain the two parallel downflanges a centrally across the plate of a sufficient depth to serve my purpose and between which the blade-actuating mechanism is adapted to operate. Thus it is seen that the space or slot between these flanges is so narrow as to be practically unnoticeable in top or outside view, while the said flanges each have several times the width of said slot; butacast plate can be made in a single piece and have flanges of any desired depth, with a suitably narrow slot. Any preferred pattern or formation of face-plate may be adopted, and the pattern may be largely varied without departing from the spirit of the invention. The said plate is in this instance made up of two sheetmetal sections united on the line of the slot between them, and each is formed with one of the two middle flanges a at its inner edge.

B represents the several register-closing sition.

double walled right angled substantially trough-shaped depression 6, having a depth somewhat in excess of the flanges a, which it .is designed to cover when the blade is closed and with which the blades have pivoted or hinged connection on pins or points 2 engaging the walls of depression 6 and the flanges a. Corresponding pivots or hinges 3 are in the same line and unite the end flanges Z) of the blades with the down-flanges a of the faceplate, so that each blade has a pivotal support at four points preferably. On these pivots said blades are adapted to hang relatively, as seen in Fig. 4, when open, and to lie in overlapped relation against the bottom of the faceplate when closed, as seen in Fig. 3. In this latter position the otherwise open slot in the face-plate walled by flanges a is practically closed by the depressions 7) overlapping the same at the bottom.

Now, having the face-plate and blades thus constructed and arranged with respect to each other, the said blades are operated by means of projections or studs8 on aslide plate or bar C, which occupies the slot in plate A between walls a, and is provided with longitudinal slots 4:, engaged by pins 2 through the flanges a, whereby said bar is permitted enough longitudinal movement to aflord blades B a quarter-turn on their pivots 2. Said blades have inclined or substantially L-shaped slots 6 in the sides of depressions b with ends or terminals 7 parallel to the bottom of said depressions, and said slots are engaged by transverse pins 8 in or on bar C. Aspring c at the side of projection 0, bearing against flange a, will serve to lock the plates in partially-open po- So it occurs when the said bar is carried in one direction its full length of operation the pins 8 run into the straight portion 7 of slots 6 and not only close said blades, but by running into portions 7 look the blades closed; but when carried the opposite direction the pins 8 run into inclined slots 6 relatively, as seen in Fig. 4, and open said blades by carrying them in to a vertical position edgewise.

I show the face-plate in conjunction with a frame D in several of the views, and said frame is adapted especially to be used when Elle register is set into a wall rather than in a cor.

The depressions b are necessarily shortened at one end where the blades overlap and an underlapping edge is seen at 5 Fig. 6,where the immediate edge is thrown down to engage beneath the next blade at the front.

What I claim is* 1. In hot-air registers, a face-plate provided with a pair of flanges across its center providing an open space between said flanges, in combination with closing-blades having transverse depressions at their middle of greater depth than said flanges and adapted to inclose the same and actuating means for said blades located between said flanges.

2. The face-plate having a pair of inwardlyprojecting flanges across its center, in combination with blades pivotally supported across said flanges and provided with depressions adapted to close upon the sides and bottom thereof when the blades are closed, said depressions having inclined slots in their sides, and a sliding bar between the flanges on the face-plate operatively engaged with said blades through said inclined slots.

3. The face plates having two inward flanges across its center, in combination with blades having walled depressions across their center adapted to overlap said flanges and inclined slots in the walls of said depressions havin terminals parallel to the bottom edges of sai depressions, and an actuating-bar between the said flanges provided with lateral projections engaged in said slots, whereby the blades are opened and closed, and when said pro'ections engage in said straight terminals the blades are locked against opening.

4. The face-plate having parallel rightangled flan es across its center, a series of blades provlded each with a transverse rightangled depression at its center corresponding to said flanges and pivotally hung at one edge to said plate, said blades provided with substantially L-shaped slots in the sides of said depressions near the pivot edge there of, a bar slidably supported between said flanges and provided with projections engaged in said slots, and a frame engaged about said blades to said. face-plate.

In testimony whereof I sign this specification in the presence of two witnesses.
